Digital transformation and corporates' green technology innovation performance–The mediating role of knowledge sharing.

• Digital transformation can improve the green innovation capability and green innovation performance of enterprises. • Breaking down information barriers to share knowledge is an important measure for enterprises to carry out green innovation. • Knowledge sharing can improve the innovation capability of enterprises by breaking down information barriers. • The degree of influence of enterprise digital transformation on enterprises of different natures varies. We analyze the effects of corporate digital transformation on green technology innovation performance by studying data from A-share listed companies from 2012 to 2022. We utilize fixed-effect and mediation-effect models to understand the underlying mechanisms. The results indicate that digital transformation significantly enhances a corporate's green technology innovation performance. Corporates' knowledge sharing plays a crucial role in mediating the relationship between digital transformation and green technology innovation performance, since digital transformation promotes knowledge sharing and thus improves green technology innovation performance.
